About a year ago when I got my gaming PC my WEI was 7.8, with only one parameter falling short of the 7.9 ideal. Now, I notice that it has fallen to 7.7 (with another parameter at 7.8, the rest 7.9). As far as I can tell, I'm running the same amount of (minimal) background processes, so it should have the same score. Does the WEI standard against which my system is being measured increase over time, or is there something that has changed on my end to account for this decrease in performance, and if the latter, any ideas how I can isolate/fix it?
